Enter whole numbers greater than 1.
Common prime factors are underlined and written in green.
GCF is equal to the product of the common prime factors.
Prime factorization of 24 :
(24 = 2 × 2 × 2 × 3)
Prime factorization of 30 :
(30 = 2 × 3 × 5)
Common prime factors of 24 and 30 are 2 and 3. GCF is equal to the multiplication of these prime factors.
GCF(24, 30) = 2 × 3 = 6
In addition to the cake method, we can calculate the GCF of two numbers by using the prime factorizations of these numbers.
Once we find the prime factorization of the given numbers by using the factorization tree or the upside-down division method, we can mark the common prime factors. The product of the prime factors is equal to the GCF od the given numbers.
